You have a good point in that banning alcohol could lead to situations where a sister is off getting drunk elsewhere - where at best there isn't a sister or good friend around to take care of her if she overindulges, and at worst there is someone present who takes advantage of the situation.

I think you've got a good plan, having dry sisterhood activities and sober drivers. I still suggest that when you do get together to drink, you limit the amount of alcohol that is available, and be sure that there's plenty of soda, water, coffee, etc. to be had. When the booze is gone, it's gone.

We also had a segment on alcohol as part of our new member education. If AST doesn't already do that, you might want to consider adding it.

There was a fraternity at my school that had a brother who was a recovering alcoholic... They made sure that one party every semester was dry. It wasn't well attended - but it was a great show of support for their brother.

I'm not sure I can be of much more help. My chapter didn't have a house, and most of my sisters either don't drink or only drink socially.

You asked about standards... AEPhi mandates that each chapter have a standards board that addresses issues ranging from a sister representing herself (and hence the sorority) badly in public, to a sister not meeting her obligations (like skipping out on recruitment events), etc. I thought most orgs had something similar... though with only 25 sisters it's probably not so necessary unless it's mandated or there are specific problems.
